Large Ultracapacitor Cells

The latest addition to the Maxwell Technologies K2 series of ultra-capacitor cells is rated 2.85 V and 3400-farad. The ultra-capacitor cell increases the range of available specific power and stored energy in the industry-standard 60 mm cylindrical K2 form factor, and introduces DuraBlue Shock and Vibration Technology, the newest innovation in ultra-capacitor reliability and performance. DuraBlue Technology is tested to some of the most demanding environmental requirements for transportation, increasing vibration resistance by approximately 300 percent and shock immunity by 400 percent when compared with ultra-capacitor-based competitive offerings.

Unlike batteries, Maxwell ultra-capacitor products store energy in an electrical field that is larger than that of a capacitor meaning ultra-capacitors have greater energy storage capacity than capacitors. This electrostatic energy storage mechanism enables ultra-capacitors to charge and discharge in as little as fractions of a second, perform normally over a broad temperature range (-40 to +65 °C), operate reliably in hundreds of thousands or more duty cycles and resist shock and vibration. Maxwell offers ultra-capacitor cells ranging in capacitance from one to 3400 farads and multi-cell modules ranging from 16 to 160 volts, which have proven to deliver high power, whether used alone or paired with batteries, in a variety of applications from automotive or industrial to consumer electronics, transportation and beyond.
